INVENTOH WITESSES ATTORNEY UNITE TATE PAT CHARLES RABB, OF DAVID CITY, NEBRASKA.

BRICK AND MORTAR WARMER.

Application filed October 24, 1916.

To all whom it may concern:

Be it known that I, CHARLES RAGE, a citizen of the United States, residing at David City, in the county of Butler and State of Nebraska, have invented certain new and useful Improvements in Brick and Mortar I'Varmers, of which the following is a specification.

This invention has relation to heating apparatus, and the nature and objects thereof will be readily apparent to those skilled in the art to which it appertains in the light of the following explanation of the accompanying drawings, illustrating what I now believe to be the preferred embodiment, or mechanical expression of my invention, from among other forms and arrangements within the spirit thereof, or the scope of the appended claims.

However, an object of the invention is to provide a heating apparatus for warming mortar and brick when building operations are conducted in the winter, thereby preventing freezing of the mortar, and insuring that the same may firmly set when used as the binding a ent between the bricks.

Another '0b160t of the invention which follows from the foregoing, is to provide, an apparatus having a series of compartments to receive the brick, and a supporting platform to receive the mortar, the platform and compartments being heated from a single source, or a burner.

A still further object of the invention is to provide in an apparatus of the character described, a rotatable element divided into compartments for receiving the bricks, said element being in addition supported upon rollers whereby it may be rotated to bring one of its compartments into registration with an opening in the casing of the apparatus, through which the bricks may be inserted.

In addition to the foregoing my invention comprehends improvements in the details of construction and arrangement of parts to be hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanying drawings, in which similar and corresponding parts are designated by the same characters of reference throughout the several views in which they appear:

Figure 1, is a view in side elevation of a heating apparatus, constructed in accordance with my invention.

Specification of Letters Patent.

Patented Nov. 2'7, 191?.

Serial No. 127,432.

Fig. 2, is a view thereof in plan partly broken away to show the interior.

Fig. 3, is a vertical section taken on the line 83 of Fig. 2.

Fig. 4, is a view in plan of the inner rotatable element for receiving the bricks, and

Fig. 5, is a view in side elevation of the member shown in the preceding figure.

Fig. 6 is a view in perspective of a central member of the device.

With reference to the drawings, the apparatus comprises in its essentials an outer cylindrical drum 1, closed at its lower portion by means of a bottom 2 provided with a central aperture 3, the sides of the drum being formed at uniformly spaced intervals throughout its circumference with openings 4, normally closed by arcuate sliding doors guided for movement in upper and lower curved guide-ways 6.

An inner rotatable drum 7 is provided within the outer drum, and is closed at its lower portion by means of a bottom 8, having a central aperture in which is mounted a vertically extending tubular fine 9. Upon,

the under face of the bottom there is further provided diverging arms 10 formed at their extremities with bifurcated portions 1.1 in which the supporting rollers 12 are journaled for rotation. At the intersection of the ra dial arms 10 centrally of the rotatable mem her, they are seated within cutaway portions 13 in the plug 14, shown to advantage in Fig. 6, said plug having a depending reduced portion 15 which is seated within the central opening 3 of the bottom 2. In this manner the rotatable member is guided and is permitted to rotate upon its supporting rollers 12, its position relatively to the outer member being maintained by reason of the engagement of the plug in the opening as above set forth.

A fuel supply pipe 16 extends radially beneath the bottom 2 and centrally thereof and is provided with a vertical member 17 which extends through an aperture in the block 14, and an alined aperture at the intersection of the radial members 10, the upper end of the fuel supply pipe being further provided with a burner or the like 18 which is located within the vertical flue 9. The inner rotatable drum 7 is provided with a plurality of radial partitions 19 which are connected at one vertical edge to the flue 9 and at their outer vertical edges to the walls of the drum 7. The lower edges of the partitions 19 may be also bent laterally to provide means for securing the same to the bottom of the drum. In a manner similar to the outer drum there is provided in the walls of the inner drum a plurality of uniformly spaced openings 20 disposed circumferentially around the drum, and in one position thereof are designed to be in registration with the openings of the outer drum, and as said openings are in communication with the compartments formed by the partitions, it is obvious that bricks or other building material may be inserted therein.

The upper portion of the inner drum is covered by means of a deflecting plate 21 which however is circumferentially spaced at its periphery from the upper edge of said drum in order to provide an annular space for a purpose to be presently noted. The deflecting plate 21 is furthermore provided with a central opening 22 which is in vertical alinement with the flue 9. The outer drum 1 is also provided with a closure upon the upper portion, which consists of an annular flange 23 designed to encompass the upper annular edge of said outer drum and having a circumferential crimped portion 24 to provide a shoulder whereby clownward movement of the same is limited by engagement of said shoulder with the drum, and also to provide a support for the plate 25 upon which the mortar may be deposited as indicated at 26.

In View of the foregoing, it will be obvious that after the compartments in the inner drum are supplied with their quota of bricks or other building material and the desired quantity of mortar has been deposited upon the plate 25, the fuel at the burner 18 is ignited, and owing to the provision of a plurality of openings 27, provided adjacent the lower portion of the drum, air is drawn through said openings and upon entering the flue 9 becomes heated. The heated air ascends, and upon reaching the deflecting plate 21 which is vertically spaced above the upper edge of the flue 9, the heated air partly enters the opening 22, and partly the compartments in the inner drum, the plate 21 serving to deflect the heated air therein. The heated air after passing through said compartments then leaves the same by means of the annular space defined by the deflecting plate 21 which as aforesaid is spaced at its periphery from the upper edge of the inner drum the heated air thus obtains access at two places to the space beneath the plate 25 which is vertically spaced from the deflecting plate 21. The plate 25 thereby becomes heated and consequently imparts its heat to the material deposited thereon. The

inner drum may be filled by inserting the material through one of the doors in the outer drum, rotating the inner drum to bring each of its openings 20 in alinement with the openings 4: for the purpose set forth. If it is desired to fill the inner drum without rotating the same, each of the openings 4 in the outer drum may be uncovered by sliding away its respective door, whereby the inner compartment will be exposed. Thus it will be seen that I have provided a simple and novel form of heating apparatus whereby bricks and other building material and mortar may be warmed subsequent to using the same.

While I have illustrated and described my invention with some degree of particu larity, I realize that in practice various alterations thereover may be made, and I therefore reserve the right and privilege of changing the form of the details of con struction and arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a heating apparatus, an outer stationary drum, an inner rotatable drum, divided into a plurality of material receiving compartments, a plate on the upper portion of the drum forming a closure thereof and spaced vertically from the inner drum, a heating flue centrally disposed in the inner drum and in communication with its compartments and the space beneath the plate, and a heating element within the flue.

2. In a heating apparatus, an outer drum having a plurality of normally covered door openings, an inner drum mounted upon rollers for rotation within the outer drum, a plurality of radial partitions in the inner drum forming compartments therein, a central heating flue having its upper portion in communication with the compartments, a plate forming a partial closure for the inner drum, a second plate forming a closure for the outer drum and spaced vertically from the first mentioned plate, and a heating element within the flue to cause vertical circulation of the air Within the flue and its entrance into the compartments and the space between the two plates for the purpose set forth.

In testimony whereof I afliX my signature in presence of two witnesses.
